Tom Brady so obviously is an alien. We’re talking the extra-terrestrial kind, not the kind that sets Congress aflame.

You simply cannot play football this long at this level and be of this earth.

You’ll know this for sure one day when Neil deGrasse Tyson writes his definitive biography.

Peyton Manning was 39 when he won his last Super Bowl and looked every year of it. He practically creaked like a rusty gate when he broke the huddle. His passes began resembling birthday balloons.

And yet here is a quite-robust Brady at 40, an age when players are supposed to be cutting pizza ads and working from the safety of football’s deer stand, also known as the broadcast booth.

He looks like he’s still playing on his first contract.

He’s playing at an MVP level when he should be closer to playing to an AARP level.

You keep waiting for Brady to show some signs of calendar-based deterioration. An earthly mortal would be making some concessions to the passing of years by this time. All he’s doing, after having won five Super Bowl rings, is throwing perfect spirals and ordering a new display case for his next five rings.

Life after 40 for most athletes is not supposed to be this many flavors of sweet. They work off a different time clock than the rest of us, the hour hand spinning more like a mower’s blade. The average span of an NFL player’s career is a little more than three years. Brady, working on his 18th season, barely cleared his throat in that time.
